The journal
Every tweak is backed up before it is applied. One-click revert restores the whole system, even after a crash or a power cut.
One-click revert
Backup, tweak, play, revert: every change is reversible
- 1
Backup
The journal records what will change and its old value before anything is touched.
- 2
Tweak
Only what you ticked, and only what the guardrails allow. Windows protection is never touched.
- 3
Play
Nothing is injected into the game, and no game file or in-game setting is edited.

Revert
When you quit, when you press Restore, or at the next sign-in after a crash or a power cut.
177 → 0On our test PC, 177 settings were applied, then undone with one press: zero differences left.
354 Windows settings, each with its undo. Each one explained in plain words before you tick it, and undone in one press.
Honest labels
Every setting says what it really does
Most Windows gaming tweaks shared online change nothing you can measure. The tool says so, and keeps the unproven ones in a Lab tier until a measurement on your PC says otherwise.
Tidier and safer, with no speed promise. Most settings carry this label.
Takes away something that interrupts a frame now and then.
Makes the time from your hand to the screen steadier.
Gives the game processor time or memory it keeps for the whole match.
In the same app
Six more pro tools, built in
Built-in FPS benchmark
Don’t take our word for it: it proves the gain on your own PC, with and without, round after round.
It plays the same spot of your game with the tool and without it, round after round, until the gap is clear: about 6 to 15 minutes. Stand still in a training area and stay in the game. After every round everything is put back.
DPC latency check
One minute of play shows which drivers hold the processor, next to your last reading.
You play for one minute while it counts; nothing on the PC is changed. It lists every driver that held the processor for more than half a millisecond, and says whether today is better or worse than your last reading.
In-game overlay
FPS, frame time, CPU, RAM and ping, drawn by RTSS inside the game on a key you choose.
RTSS draws it; you get RTSS from its official page, and the tool installs nothing by itself. Tick the readings you want, keep your own RTSS layout if you have one, and place it top left, centre or right.
NVIDIA driver settings
Optional driver settings, each one explained before you tick it and each with its undo.
Read from the driver’s own profile store. Each value is saved before it changes, so one press puts the driver back exactly as it was.
Lighter Discord and browsers
Discord stops drawing on your graphics card, and closed browsers stop running in the background.
Discord keeps drawing with the graphics card and starts with Windows; Chrome, Brave, Edge, Vivaldi and Opera keep running after their last window closes. The tool turns these off and keeps the old values, so one button brings them back.
Scan and repair Windows
Wi-Fi, sound, websites and devices are checked, and only what is broken gets fixed.
Wi-Fi, websites, sound and devices are each tested first. When nothing is wrong, nothing is changed. The full check of a Windows that acts broken takes about three minutes.

Is it safe with game anti-cheat?
It changes Windows, never the game. Nothing is injected into a game and no game file or in-game setting is edited.
What if a change breaks Windows?
Every change is journaled first. Restore puts it back, and a session cut short by a crash is put back at your next sign-in.
Does the optimizer overclock?
No. It leaves clocks, voltages and fan curves to the tools you already use.
What does the optimizer never delete?
Your files, game saves and browser passwords. Anything that cannot come back asks you first.
Which Windows does it need?
Windows 11 and an administrator account for the system-wide changes.
Will it close Discord or my stream?
Apps you use during a match, such as Discord, SteelSeries Sonar or MSI Afterburner, are flagged and left unticked. You choose what stays open.
Does it install a driver?
No sensor driver of its own. Live readings come from MSI Afterburner when it is running.
What if I decline the administrator prompt?
Nothing is changed, and the tool says so. Only system-wide changes ask for it.
Which games does it work with?
Games from nine stores are found by themselves, and any other game can be added by its program file.
